I had assumed that since "The" is part of the Reach's proper name, it should be capitalized... but I'm starting to think it should be lower case after all. Looks better that way. We should do a search-and-replace for this.

Sky_qRe_KW01_Aladoer in Karthwasten, Ruby Drake Inn, on 'Direnni registers', says 'You don't have any with you' despite having Codex Mania 'Sky_iRe_kwtunnels_Direnni_book1'. Same answer with the patterns 'T_Bk_DirenniEmpty02SHOTN'. Did manage to sell him Numalchemy 'Sky_qRe_KW01_register02', however after refusing once he never said anything about a lower offer but only gave 1000 gold instead of 1200. Either way these are actually bad deals given that the books are valued 1800. If he pays less than someone with non-low Barter could get, there must be another benefit to bringing them to him?"

Also did you decide to do away with generic "Background" and "my trade" entirely (certainly one way to deal with the oversharing issue...) or is it just that they haven't been added for the Sky classes?

These error reports are very helpful. Hopefully we can fix most of these for a patch later this month.

Aurius will offer travel services in the future, once there are places for him to take the player, like Markarth and Beorinhal. If we offer fast travel between Karthgad and Karthwasten, I'd rather use their river docks.

Sounds like the Direnni register quest needs further playtesting and fixing. The registers themselves should definitely be priced lower, and the amount Aladoer pays for them might be a tad high too.

Background topics for generic NPCs haven't been implemented yet. We can add them in the next patch. My trade topics haven't been added either, though frankly I'd rather leave those out, sine they don't really give much useful information, and I like avoiding too much clutter in the dialogue box.

I imagine the Dwemer ruins are supposed to be blowing steam. The Dwemer built things to last, after all.
